CVE-2026-1471
Excessive caching of authentication context in Neo4j Enterprise edition versions prior to 2026.01.4 leads to authenticated users inheriting the context of the first user who authenticated after restart.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
Description
Excessive caching of authentication context in Neo4j Enterprise edition versions prior to 2026.01.4 leads to authenticated users inheriting the context of the first user who authenticated after restart. The issue is limited to certain non-default configurations of SSO (UserInfo endpoint). We recommend upgrading to versions 2026.01.4 (or 5.26.22) where the issue is fixed.
